fully cuougli to show the actual cost of power by the preseut methods iu 

 use iu the district. At present my data on the value of the machinery and 

 plants and the. rates of taxation, insurance, etc., on the same is not complete 

 enough to give Kny but a very approximate figure. 



Engaged in the stone industry of the county there are twenty-nine 

 operating companies controlling twenty-six mills and sixteen quarries. 

 They use approximately 5,000 H. 1'. and 4,000 tons of coal per month in its 

 [trodudtion. 



For convenience in studying the probltm of power production of the 

 countj' I have divided it into three districts as follows : 



District No. 1 includes all the plants in and around EUetsville and 

 Stinesville. This district is conti'oUed by six companies running six mills 

 and two quarries. They use approximately 1,000 H. P. and 750 tons of 

 coal to generate the power. 



District No. 2 includes the quarries and mills (;f lUoomington and 

 Hunter ^'alley. This district is controlled by eleven companies running 

 eleven mills and five quarries. They iise 2,000 H. I', and 1,700 tons of coal 

 lier month in its production. Two of the plants of this district buy electri- 

 cal power from the Central Indiana Lighting Co. of Bloomington, and in 

 figuring the coal consumption for the district I have added the amount of 

 coal they would use in the production of their power if they worked undei' 

 the same conditions as the other operators of the distinct. 



District No. '■> includes the rest of the county, that is, all the mills and 

 quarries around Clear Creek and Saunders Station. In this district there 

 are twelve operating companies running nine mills and nine quarries. 

 They use approximately 2,000 H. 1'. and consume 1,050 tons of coal. 



In looking for improved methods of power production the following 

 possibilities present themelves : 



First, each operator can make an effort to produce as much of his 

 power in a single unit as possible, and distribute the powei to the differ- 

 ent machinery of his plant electrically. This method is becoming more and 

 more common in the stone mills of the county, but very little effort has 

 been made toward the use of electrical machinery in the quarries. 



At least two of the operators of tlie district are using compressed air 

 to drive their quarry machinery, but a careful study of the costs of power 

 production in this form shows that the fuel cost is materially raised, 

 although the advantages of such a system are : Small waste in handling
